thick enough for this purpose as they have to contain a considerable thickness ofl insulating material. f v i i Arfurther object of my invention is to provide 'with this fconstruction a means whereby the waste pipe is readily accessib1e,a removable cover plate being furnished within the refrigerator'casing and 'covering-theslot in which the waste pipe is contained.

My invention consists of a refrigerator incorporating a waste pipe receiving construction all as hereinafter more particularly described and illustrated in the accompanying drawing in which:

Fig. 1 is a perspective view of a fragmentary portion of the rear wall of my refrigerator casing, together with a fragmentary portion of the rear Wall of the sink positioned upon the top of the casing, showing the drain pipe depending from the sink.

Fig. 2 is a reduced perspective view of a fragmentary portion of the refrigerator casing containing the slot in which the waste pipe is contained.

Fig. 3 is a perspective view of the cover plate forthe slot in the refrigerator casing, and

Fig. 4 is a fur-ther reduced vertical cross sectional view through the refrigerator and sink, showing the waste pipe contained Within the top :'40 and rear walls of the refrigerator casing.

Like characters of reference indicate corresponding parts in the different views of the drawing.

The combination unit consists of a refrigerator casing 1 having a sink 2 positioned upon the top thereof, the casing having insulated walls and an insulated top 3 which is in the proximity to the bottom of the sink, the skirt 4 of the sink sitting upon the top of the refrigerator, all as clearly shown in Fig. 4.

The sink 2 is furnished with an L-shaped waste pipe 5 which extends from an elbow 6 communicating with the sink rearwardly within the top 3 of the refrigerator casing and down the back 7 of the casing, the waste pipe being positioned Within the top and vrear walls in an L`shapedslot 8.. The bottom of the Waste -pipe isconnected to the usual U-shaped trap 9` which is provided with anv elbow 10 extending rearwardly from the rear wall of the casingand adapted to be suitb ablyconnected asin standard practice, the trap 9 being also contained` within the slot 8.

, The waste pipe is shielded'and the slotaifclosed to the interior of the casing by means ofra substantially L-shaped cover plate 11 which is 6'5' formed of inner and outer walls 12fand 13', hav- `ing a layerllfly of non-conductive material, such asfor'example cork, positioned' therebetween.

VThis L\shaped member is of a greater. width thantheslot'il and` also ofl a greater length and '70 is formed with roundedouter .edgesv so that it presents a A'finished and attractive appearance `whenin position withinthelcasing.

In order to obtain an air tight and non-conduct# ing joint between the plate 11 and the walls of 75 the refrigerator I provide a rubber or similar moulding 19 positioned around the edge of the slot 8 and similar moulding 20 positioned around the edge of the inner face of the plate 11.

When the plate is in place the moulding 19 bears against the inner face of the plate and the moulding 20 against the inner faces of the casing walls so that a tight joint is obtained. For retaining the cover plate tightly in position I furnish a pair of eccentrically mounted cam-like members 15 which are positioned upon the faces of the top and rear casing walls to engage the edges of the plate 11, engaging plates 16 being furnished in the edges of the plate 11 for this purpose. The cam members 15 are pivotally mounted upon pins 17 and are furnished with handles 18, so that they can be swung against and away from the plate 1l.

The inner vertical face of the cover plate 11 carries an angle piece 21 which is of substantially Vthe same width as the slot 8 and adapted to rest upon or lie in close proximity to the bottom of the slot. This angle piece is furnished as a means for supporting the cover plate when it is being inserted in position and also has a function in covering the joint between the lower edge of the slot and the back of the plate, so that any moisture that might conceivably form upon the outside of the waste pipe and drop therefrom into the bottom of the slot 8 would not run into the seating 105 of the moulding 19 against the back of the plate;

By the provision of the mouldings 19 and 20 the cover plate 11 is retained out of contact with the walls of the casing, and as the casing and cover P1955@ are formed with metal walls this is a very 11A-0 desirable feature as a metal to metal contact is avoided with the consequent possibility of heat conduction.

It will thus be seen from my construction as herein set forth that the Waste pipe is contained within the thickness of the refrigerator Walls and is effectively insulated from the interior of the refrigerator by the provision of the detachable cover plate 11, the Waste pipe being at the same time exposed to the outer air. If it is at any time desired to obtain access to the waste pipe it is only necessary to move the cam members 15 out of contact With the cover plate when such plate can be removed to expose the waste pipe within the slot.

From the foregoing description it will be apparent that I have devised a very simple and practical construction wherein the waste pipe and trap in a refrigerator sink unit are contained within the thickness of the refrigerator walls, thus avoiding the necessity of having the waste pipe projecting into the refrigerator and taking up valuable space, and although I have shown and described a particular embodiment of my invention it is to be understood that I can make such changes and alterations as I may from time to time deem necessary Without departing from the spirit of my invention set forth in the appended claims.

What I claim as my invention is:

1. In a refrigerator casing adapted to be placed beneath a sink and having a slot in the casing wall in which the Waste pipe is contained Within the thickness of the Wall, of a plate detachably secured in front of the inner face ofthe slot containing wall and covering the slot.

2. In a refrigerator casing adapted to be placed beneath a sink and having an L-shaped slot extending through the top and back Walls of the casing and in Which the projecting Waste pipe is contained within the thickness of the walls, of a plate detachably secured in front of the inner faces of the top and back Walls and covering the slot.

3. In a refrigerator casing adapted to be placed beneath a sink and having an L-shaped-slot eX- tending through the top and back Walls of the casing and in which the projecting Waste pipe and its U trap is contained Within the thickness of the walls, of a plate detachably secured in front of the inner faces of the top and back walls and covering the slot.

4. In a refrigerator casing adapted to be placed beneath a sink and having an L shaped slot extending through the top and back walls of the casing and in which the projecting waste pipe and its U trap is contained within the thickness of the Walls, of an integral L-shaped plate detachably secured in front of the Walls and covering the slot.

5. In a refrigerator casing adapted to be placed beneath a sink and having a slot in the casing wall along the length of which the Waste pipe extends, f
